Kevin, Apart the input device That 340 , do we need match the transistors? If use jets input like 2sk170 and j74, are there any change to the resistor values of the input stage circuitry? Thanks

Thanks

Hi Gilmore Sir, For this CFA pcb version, Please instruct how to select SS and ZF . Are SS and ZF activated by shorting the labelled jumpers? Can SS and ZF option be activated at the same time? Thanks again

Please post the gerber file Many thanks
